Hi Hans,
PC/XT class
machines generally have no clock hardware
in them as standard....
This is only true if you look at the very basic unit....
But that's exactly what I was talking about, STANDARD PC/XT machines. IBM, to
the best of my knowledge, never released any form of clock card for the PC or
XT.
....but clock-cards have been popular back than. Either
as single
function card (rather rar) or within a multi function card.
I used to have at least one clock card and several multi-function cards with
built in clocks for use in such machines.
The point is though that even though they were popular, they were generally the
exception rather than the rule....
TTFN - Pete.
